SPAM-based recipes for continuum simulations

Smooth Particle Applied Mechanics (SPAM) is a technique which provides a versatile approach to simulating many difficult problems in continuum mechanics, such as the breakup of a cavitating fluid and the penetration of one solid by another. SPAM also provides a simple evaluation method for all the continuum variables, as well as the spatial gradients required by the evolution equations. This global evaluation simplifies interpolation, reasoning, and Fourier transformation. Because SPAM is so flexible and easy to program, it should be included in the toolkit of anyone doing simulations.
